USDC vs USDT: A Tale of Two Stablecoins and Their Regional Romp

by

Ah, the delightful dance of digits! Circle’s USDC, that paragon of regulatory virtue, has pirouetted past the $80 billion mark in circulating supply, while gracefully overtaking Tether’s USDT in adjusted transaction volume for the first time since the quaint year of 2019. How charming!

New country-level ownership data, a veritable tapestry of financial intrigue, reveals USDC leading in several individual markets. It seems the stablecoin race has splintered into a regional ballet, each market a stage for its own dramatic performance, rather than a singular global spectacle.

USDC vs USDT: A War of Wits and Wallets

Tether’s USDT, the erstwhile titan of the stablecoin sector, with its market capitalization of roughly $184 billion, remains more than twice that of its nearest rival. Yet, one cannot help but notice the winds of change. Together, these two stablecoins account for approximately 93% of the total stablecoin market capitalization, according to the ever-watchful TRM Labs. How positively monopolistic!

However, the competitive tableau has shifted dramatically in early 2026. According to the sage data from CoinMarketCap, USDC’s circulating supply leapt from a mere $70 billion in early February to $75 billion at the start of March, before breaching the $79 billion barrier. A pace so swift, it leaves one breathless!

Meanwhile, the erudite researchers at Mizuho Financial Group, in a report published on March 13, revealed that USDC has processed approximately $2.2 trillion in adjusted transaction volume year-to-date, compared with a mere $1.3 trillion for USDT. USDC, it seems, has seized 64% of the combined adjusted volume, a dramatic reversal from the 2019-2025 period when USDT reigned supreme, and USDC languished with a mere 30%.

Mizuho, ever the arbiter of financial propriety, defines adjusted volume as transfers involving centralized exchanges, decentralized exchanges, and other identified entities that represent genuine value transfers, rather than the banal automated or repetitive activity.

A Fragmented Race: Country-Level Data Unveiled

A separate dataset from BVNK’s Stablecoin Utility Report 2026, compiled with YouGov across 4,658 respondents in 15 countries, adds another layer of complexity. Lisk Head of Research Leon Waidmann, with his keen eye for detail, highlighted USDT versus USDC ownership rates across these markets.

Nigeria, that vibrant economy, led all countries with 59% USDT ownership, compared with 48% for USDC, a testament to the stablecoin’s deep roots in economies with volatile local currencies. USDT also led in India, the Philippines, Singapore, Thailand, Argentina, France, and the United Kingdom. How très chic!

Yet, in five markets, USDC ownership actually exceeded USDT. Colombia, with its 29% USDC ownership versus 25% for USDT, South Africa with 29% versus 23%, Germany at 17% versus 15%, Brazil at 16% versus 14%, and the United States at 26% versus 22%. A veritable coup for USDC!

“USDT vs USDC ownership by country. Ranked… USDC is catching up. In Colombia, South Africa, the US, Germany, and Brazil, USDC ownership actually exceeds USDT. The regulated stablecoin is gaining ground,” wrote Waidmann, with a flourish of his quill.

The pattern suggests that regulatory positioning may be influencing adoption. USDC, issued by the impeccably compliant Circle Internet Group, holds licenses under both Europe’s Markets in Crypto-Assets (MiCA) regulation and aligns with the US GENIUS Act framework. Tether, on the other hand, has taken a different approach, opting out of MiCA compliance and concentrating its growth in Asia and other non-Western markets. How delightfully rogue!

“When MiCA becomes safer for consumers and stablecoin issuers, then we might reconsider,” quipped Paolo Ardoino, with a wink and a nod, on July 23, 2025.

Capital Flight and Transaction Trends: The Plot Thickens

The supply surge carries a geopolitical dimension, as Dubai-based analyst Rami Al-Hashimi astutely observed. He noted that over-the-counter desks in Dubai have struggled to keep up with USDC orders amid sharp declines in Dubai’s real estate market. The DFM Real Estate Index fell roughly 31% from a recent peak of around 16,800 to about 11,516, according to TradingView data. A dramatic fall from grace!

Token Metrics, ever the sage observer, noted that when investors in oil-rich economies move into USDC rather than traditional dollar accounts, it signals that the digital form of the dollar is competing with its physical form. How positively futuristic!

“USDC market cap is approaching a record $80 billion, with analysts pointing to capital flight from the UAE as a driver.

This one deserves a second look. USDC near $80B is a milestone, but the UAE angle is the real story.

Capital flight into dollar-denominated stablecoins from a… ” – Token Metrics (@tokenmetricsinc) March 14, 2026

Mizuho analysts Dan Dolev and Alexander Jenkins, in their research note, argued that adjusted volume may matter more than market capitalization when predicting the long-term stablecoin winner. They raised their Circle stock price target from $100 to $120, citing expanding USDC use cases in prediction markets and agentic commerce. How prescient!

The stablecoin market overall has reached a record $315 billion as of mid-March, reflecting growing institutional demand across both trading and non-trading applications. Whether USDC can sustain its volume lead while narrowing USDT’s capitalization gap will depend on how quickly regulatory preferences and regional adoption patterns continue to fragment the stablecoin market. The answer, it seems, will vary from one country to another, like a financial mosaic.
